USBA Ports not working at delivery Mac Pro 2020

I'm not sure if there's something I'm supposed to do to enable the port but my USB A ports aren't working. Anything from what I can tell isn't working on that port. Thats at the top of the tower ports on my Mac Pro 2020(2019 I know lol) I've confirmed in the System report that it recognizes that of the 8 PCI card slots, 2 are in use. One of which is the port that my AMD Graphics card is plugged into. I ASSUME the only other device that's using it is the mentioned USB A card. There isn't anything that I've just installed or anything I've just received the unit.

Your assistance is greatly appreciated.

You could try powering off an re-seating the card in its PCI-e slot. If you disconnect the AC power for a quarter minute or more while you do this, that will effect an SMC reset as well.

Next step is to contact support.

Thank you... it turns out that for some odd reason my external LG DVD Writer just won’t work plugged Into that USBA slot. But everything else I’ve plugged in there works 🤦🏾‍♂️ But I plugged a Thunderbolt 3 dock into a port and then plug my DVD Burner into that it shows up 😅 Weird... but I assume it has something to do with the power available on that slot 🤷🏾‍♂️ Thank you anyway.
